Answer 2

$(c) \: 35 \: cm\\ (d) \: 136 \: cm$

Step-by-step explanation:

$(c) \: perimeter = \: 2cm+(5cm+5cm)+(4cm+4cm)+(3cm+3cm)+9cm \\ = 2cm+10cm+8cm+6cm+9cm \\ = 35cm \\ (d) \: perimeter = 24cm+(20cm+20cm)+(6cm+6cm+2cm)+4 \times (20cm-8cm)+(24cm-6cm-6cm-2cm) \\ = 24cm+40cm+14cm+4 \times 12cm+10cm \\ = 24cm+40cm+14cm+48cm+10cm \\ = 136cm$
